I totally agree with you.  Some of the students I teach have learning disabiltiies.  When I informally assess their reading abilities some are fifth grade students who can read only on a second grade level.  I could do test prep all year long and it would still be completely unrealistic to expect one of these students to pass an end-of-year test.  And now the state of North Carolina wants to use my students test scores as part of my evaluation results?!?!?  Or how about the students who are perfectly capable of being successful but instead make bad choices and blow their chance to do well on the test.  Again, the effort they put forth on a test is going to be reflected in evaluation rating?!?!?  If only the people making the decisions about testing and evaluations were teachers in the classroom.
